I have no problem with this. Specializing on two positions (ILB) should be what he is better at than running an entire defense.

Quote:

Bill Sheridan has been named inside linebackers coach by the Miami Dolphins.

Sheridan joins Miami after spending last season as the defensive coordinator of the New York Giants. He spent the previous four seasons as the team’s linebackers coach. Prior to joining the Giants, Sheridan spent three seasons at the University of Michigan, the first as linebackers coach and the last two as defensive line coach. He was also the school’s recruiting coordinator in 2002-2003 and netted a pair of classes that were rated among the 10 best in the country.

Sheridan began his coaching career at Shrine High School in Royal Oak, Mich. from 1981-84. He was then a graduate assistant at Michigan for two seasons before coaching linebackers at three schools - Maine, Cincinnati and Army – from 1987-95. In 1996 and 97, Sheridan coached the defensive backs at West Point. He then put in a three-year stint as the linebackers coach at Michigan State. Sheridan spent the 2001 season at Notre Dame, where he coached safeties and special teams. He moved to Michigan the following year.

A native of Detroit, Sheridan earned four letters as a linebacker at Grand Valley State University. He graduated from De La Salle High School in Detroit. Sheridan and his wife, Jaycine, have four children: Joe, Nick, Mark and Natalie.
